Ecology, biology and other LifeSciences overlap with zoology and geography, which describe the things that ecology tries to predict, and energy economics which describes mostly human food chains and trophic levels.

Sometimes ecology is compared to anthropology, because both use a lot of methods to study one thing we cannot live without.

Mathematics is crucial for Ecology, for example for the calculus, statistics, projections and extrapolations when Ecologists deal with specific information about the number and distribution of species, the evaluation of biomass, population growth, extension of communities and biodiversity, and to quantify the environmental pressures at a given biome.

Ecology became a central part of the World's politics as early as 1971, UNESCO launched a research program called Man and Biosphere, with the objective of increasing knowledge about the mutual relationship between humans and nature.
